How Much Does a Growth Agency Cost for a $10M+ ARR Tech Company?
There's no single number — a growth agency engagement for a company above $10M ARR typically ranges from a focused single-service retainer to a full organic-and-paid program, with cost driven mainly by scope and ad spend under management, not company size alone.
What drives the cost
Three things matter most: how many services are in scope (one service vs. the full organic-and-paid program), how much media spend is being managed, and how much original content production is included versus strategy alone.
What's usually included at each level
A single-service engagement (just SEO/AEO/GEO, or just programmatic) covers strategy and execution for that one channel. A full program adds the other pillar, content production, and cross-channel reporting that ties organic and paid performance together.
Questions worth asking before you sign anything
What's included in the retainer versus billed separately (ad spend, paid tools, content production)? Is reporting weekly or monthly? What's the minimum term, and what happens if it's not working after that term?

A couple more things worth knowing.
It depends on how many channels you need covered — an agency often costs less than hiring separate in-house specialists for organic and paid, especially below a certain spend threshold.
Three months is a common starting point — enough time to test, learn and optimize before judging results.
